Siberian Kittens

The Siberian is a large, powerfully built, and athletically muscular breed. Males typically weigh 6–9 kg, with some exceptional individuals reaching 10–12 kg. Females are smaller at 4–7 kg. They have a broad, rounded head, a strong barrel chest, substantial bone structure, and remarkably powerful hindquarters that give them an extraordinary jumping ability. The Siberian is one of the slowest-maturing cats, often not reaching full physical and coat development until 4–5 years of age — longer than almost any other pedigree breed.

The Siberian coat is a full triple layer — long water-repelling outer guard hairs, a dense middle awn layer, and a soft insulating undercoat — naturally water-resistant and less prone to matting than most longhaired breeds. The breed is accepted in almost every colour and pattern: brown tabby, silver tabby, black, blue, red, cream, tortoiseshell, white, and smoke variations are all fully recognised. The only colour not accepted in the Siberian is colourpoint — that variation is classified separately as the Neva Masquerade. Coat volume and texture develop progressively, reaching full magnificence at 4–5 years of age.

Siberian eye colour varies freely across the spectrum — deep gold, warm copper, vivid green, and blue-green are all seen and all equally valid. Unlike many breeds, eye colour is not strictly linked to coat colour, which means striking combinations — a silver tabby with vivid green eyes, a black smoke with deep amber — are entirely common. White Siberians may have blue, odd-coloured, or green eyes. The only fixed eye colour in the Siberian family is the sapphire blue of the Neva Masquerade, which is governed by the separate colorpoint gene.

Despite the sheer volume of the Siberian's triple coat, it is considerably more manageable than its appearance suggests. The water-resistant, low-static guard hairs mean the coat sheds dirt readily and resists tangling far better than many other longhaired breeds. Two to three thorough brushing sessions per week are sufficient for most of the year. The exception is the twice-yearly seasonal moult — particularly the spring shed — when daily brushing is strongly recommended to manage the undercoat. Routine ear cleaning, nail trims, and dental care complete their regular needs.

The Siberian is a moderately vocal and genuinely communicative breed. They use a varied repertoire — chirps, trills, soft meows, and the occasional emphatic trill — and are conversational when engaged. They are vocal enough to feel like an active presence in the household without being insistent or demanding. Their communication is interactive rather than performative — they speak when they have something to say, and listen attentively when spoken to.

The Siberian is one of the healthiest of the large semi-longhaired breeds, with fewer known hereditary conditions than many popular alternatives. The primary health concern is Hypertrophic Cardiomyopathy (HCM). Our breeding cats are screened annually by certified veterinary cardiologists, and all kittens come with a written genetic health guarantee and full veterinary documentation. The breed's centuries of natural selection in a demanding environment have produced a robust, resilient constitution that compares very favourably with many purpose-bred pedigree cats.

With proper care, Siberians typically live between 12–15 years, and many individuals reach their mid-to-late teens in excellent health. Their longevity is best supported by regular veterinary check-ups including annual cardiac screening, a high-protein diet suited to their large, active frame, and an enriched indoor environment that keeps their considerable intelligence engaged. Their natural constitution and lack of extreme physical modifications gives them a significant health advantage over many more fashionable pedigree alternatives.

The Siberian is one of the most thoroughly documented breeds in relation to low allergen production. Multiple independent studies have found that Siberians produce significantly lower levels of the Fel d 1 protein than most other breeds — the primary glycoprotein responsible for triggering cat allergies in humans. Many people who react to other cats can live comfortably with a Siberian. This is not a guarantee — individual Fel d 1 levels vary between cats of the same breed, and individual human sensitivity varies equally. We strongly recommend an extended visit before committing if allergies are a factor.

Siberians are affectionate and physically engaged companions without being overly dependent. They enjoy being close to their people — settling nearby, following from room to room, and participating in household life with obvious interest — and are typically comfortable being picked up and held, particularly once settled in their home. They show affection in a steady, confident way: warm and genuine, but never anxious or needy. Many owners describe the Siberian as having a quality of calm, attentive companionship that sets it apart from almost any other breed they have known.

A high-protein, meat-based diet suits the Siberian's large, muscular, athletically active frame and supports both their slow-developing physique and the condition of their triple coat. A combination of premium wet food — which supports hydration and urinary health — and measured quality dry kibble works well for most individuals. Omega-3 fatty acid supplementation is particularly beneficial for coat volume and lustre, especially during and after the seasonal moults. We send each kitten home with a detailed feeding guide and the food they are already accustomed to, ensuring a smooth and stress-free transition.
